Регулярно приходится писать и ревьюить код, где используется PySide2-6. Заметил, что в подавляющем большинстве случаев настройка создаваемых базовых виджетов происходит через методы. Думаю, всем знаком такой способ. Простой пример с кнопкой: button = QPushButton("Click Me") button.setMinimumWidth(300) button.setFlat(True) button.setStyleSheet("font-size: 20pt") button.setToolTip("Super Button") button.clicked.connect(lambda: print("Button clicked")) Но есть и альтернативный способ - настройка через свойства. Это просто ключевые аргументы конструктора класса. Хоть они и не указаны в документации как аргументы, но они есть) Этот код делает тоже самое но с помощью Property button = QPushButton( "Click Me", minimumWidth=300, flat=True, styleSheet="font-size: 20pt", toolTip="Super Button", clicked=lambda: print("Button clicked"), ) Где это может быть полезно ▫️ Это выглядит более аккуратно и коротко, уже повод использовать ▫️ Может использоваться в заполнении лейаута, когда нам не нужно никакое другое взаимодействие с виджетом и поэтому сохранять его в переменную не требуется. Например, лейбл или кнопка. widget = QWidget(minimumWidth=400) layout = QHBoxLayout(widget) layout.addWidget(QLabel("Button >", alignment=Qt.AlignRight)) layout.addWidget(QPushButton("Click Me", clicked=lambda: print("Button clicked"))) widget.show() Либо так widget = QWidget(minimumWidth=400) layout = QHBoxLayout(widget) for wd in ( QLabel("Button >", alignment=Qt.AlignRight), QPushButton("Click Me", clicked=lambda: ...) ): layout.addWidget(wd) widget.show() ▫️ Можно хранить настройки в каком-то конфиге или генерировать на лету, после чего передавать как kwargs. kwargs = {"text": "Hello " * 30, "wordWrap": True} my_label = QLabel(**kwargs) Как получить полный список доступных свойств? Эта функция распечатает в терминал все свойства виджета и их текущие значения def print_widget_properties(widget): meta_object = widget.metaObject() for i in range(meta_object.propertyCount()): property_ = meta_object.property(i) property_name = property_.name() property_value = property_.read(widget) print(f"{property_name}: {property_value}") #tricks#qt

🚀 Varys Capital's Tom Dunleavy Highlights Dramatic Shift in Crypto Funding Landscape The cryptocurrency market has experienced a significant shift in its funding environment over the past six months, according to Odaily. Tom Dunleavy, Head of Venture Capital at Varys Capital, shared on X that the process for venture capitalists (VCs) to secure promising projects has changed drastically. Previously, VCs had to engage in extensive networking, content creation, podcast appearances, and numerous calls to attract investments. Now, simply having available funds is sufficient, as projects are actively seeking out VCs. Currently, most VC firms are in one of three states: they have exhausted their funds, shifted focus to later-stage investments (Series A and beyond), or are in the process of fundraising, albeit with difficulty. Fundraising timelines have extended from 2-3 weeks to 2-3 months. Projects with questionable business models or those merely replicating the latest trends are struggling to secure new or follow-up funding, which Dunleavy views as a positive development. There are fewer than 20 firms actively investing in pre-seed or seed rounds. VCs now have the luxury of selecting projects more carefully and conducting thorough due diligence. The investment cycle of 2025-2026 is anticipated to be a historic 'golden opportunity,' provided VCs can endure the current market conditions. #CryptoFunding#VentureCapital#CryptoMarket#PreSeed#SeedInvestment#DueDiligence#InvestmentTrends#CryptoVC#FundingLandscape#GoldenOpportunity
